Abstract: A phantom material may be irradiated with varying energy x-rays to determine its phase shift properties. A determination of the difference between those phase shift properties and the phase shift properties of another material of interest can be represented and stored in terms of a polynomial function. The stored function can then be used in combination with a surrogate phantom shaped in the form of another object to obtain the phase shift properties of that other object as if it were made from the material of interest.

Abstract: A method and system to determine material composition of an object comprises capturing a series of digital radiographic images of the object using a single exposure energy level. An intensity of the captured images is determined as well as phase shift differences. A difference in material composition of the object may be determined based on a combination of the determined intensity and the modulated phase shifts of the captured images.

Abstract: Embodiments of methods and apparatus are disclosed for obtaining a phase-contrast digital mammography system and methods for same that can include an x-ray source for radiographic imaging; a beam shaping assembly including a filter or a tunable monochromator, a collimator, a source grating, an x-ray grating interferometer including a phase grating, and an analyzer grating; and an x-ray detector; where the source grating, the phase grating, and the analyzer grating are aligned in such a way that the grating bars of these gratings are parallel to each other.

Abstract: A phase contrast x-ray imaging system generates an absorption image and a phase shift image of an object under study. The absorption image represents a measurement of the imaged object's attenuation of radiographic energy, and the phase shift image represents a measurement of the imaged object's phase shifting of the radiographic waves passing through the object. The two images may be used to improve soft tissue discrimination in radiographic imaging.

Abstract: An M×N array of sensor tiles are attached to a substrate using a compliant layer that includes an adhesive. A thickness of the compliant layer varies depending on a thickness of the sensor tiles so that outward facing sides of the sensor tiles are substantially aligned.

Abstract: A digital radiographic detector system includes a number of DR detectors enclosed by a housing. A base section with wheels has attached thereto a vertical column with a height adjustable horizontal arm extending therefrom. The housing with DR detectors therein is attached to a distal end of the horizontal arm. The housing comprises a major surface made from a radiolucent material to allow the detectors to capture radiographic images via x-rays transmitted through the major surface of the housing. The housing is configured to support the plurality of DR detectors therewithin.
